1. Names and functions of parts
Description of characters displayed in the temperature controller
The controller uses a display of 7-segment LED. Characters to display operation functions are
indicated in the “Measured Temp.” screen.
Character displays and corresponding meanings are described below.
Auto-stop or Auto-start operation can be selected with the TIMER key.
Character Identifier Name Meaning

has ended.
Means that the auto-start operation
has been selected.
Function to lock so as to prevent
changing of the set contents
Temperature compensatio n function
to allow the aluminum block
temperature to agree with the
control temperature (see page 23)
Function to select whether the
recovery from power failure is to be
made automatically or manually.
Select ON with the ▲ key to
activate lock to prevent change of
the setting and when the recovery
from power failure is to be made
automatically.
Select OFF with the ▼ key to
cancel locking to enable free
change of the setting and when the
recovery from power failure is to be
made manually.
Selection of the mode that is
inoperable during operation causes
display of nG in the set temperature
display, rejecting any attempt of
change.
Attempt to change the mode while
the LocK function is ON causes
display of Loc in the set
temperature display, rejecting any
attempt of change.

2.Operation Method
From mounting of the aluminum block to operation start
1. Mounting the aluminum
block
Hand grip for
aluminum block
Use the dedicated aluminum block available separately.
The use of an attached dedicated hand grip will prove convenient for
mounting/removal of the aluminum block.
Caution： ・ Possible hazard of burn. Use the hand grip when the
aluminum block is sufficiently cooled.
・ Do not raise the temperature while keeping the hand
grip left attached.
※ If necessary, a bar thermometer may be inserted into a
thermometer hole (used also for attaching the hand grip) of the
aluminum block.
(Use the thermometer of maximum 200℃ or more. Since the bar
thermometer is not attached, obtain it separately.)
Preparation
Bar thermometer
2. Connecting the power
cord
3. Installing the sample To maintain the temperature accuracy, use a sample container
4. Turning ON power
supply
5. Starting operation Press the START/STOP key of the operation panel for one second,
Connect the power cord to an appropriate receptacle firmly.
The receptacle to be connected must be of a 100V 15A type.
appropriate in size to the sample installation hole of the aluminum
block.
Turn ON the POWER switch of the mai n body and set the desired
temperature using▲▼ keys of the operation panel.

Press the START/STOP key for one second after temperature
setting, and the continuous operation begins. Pressing the
START/STOP key again for one second causes stop of
operation.

※ The temperature and timer’s set time can be changed during operation.
※ Cautions for the auto-stop operation
・ The timer does not start counting till the bath temperature reaches the set level.
・ When the set temperature is below the bath temperature, the timer does not start
counting till the bath temperature drops below the set temperature.
The operation functions of sub-menu of the product are as follows.
Keep pressing the TIMER key for four seconds. The mode changes to the sub-menu mode.

The operation function of this device is as follows.
Nomenclature Description
№
Over-temperature

preventive function
Causes activation of the timer halfway of fixed-value
operation, then automatic operation stop after the set period.
This function is used “to set the automatic stop after the set
time”, “to set, in the course of operation, the automatic stop in
several hours.”
starting the operation. In the auto-stop mode, the timer starts
counting when the set temperature is reached.
“to set the automatic start at the specified time.”
The calibration offset function is to compensate for any
difference occurring between the target bath temperature and
controller control temperature (sensor temperature).
Compensation can be made either to the positive or negative
side over the entire temperature range of the system.
This is a function to select automatic or manual return to the
operation state after power failure.
Automatic return with
OFF
The automatic over-temperature preventive function is
incorporated.
When the bath temperature rises excessively along with the
set temperature of the device, this is set to activate
automatically at +12℃.
Stop operation when this function is activated. The Alarm
lamp flashes. To cancel, turn ON the power switch newly
again (manual reset).
